The PX20 is the smallest programmable 2D Bluetooth data collector. With a fast integrated 2D CMOS scanner and when fully charged, offering operating times of up to 35 hours. In occasions where Bluetooth is not provided, access by the USB port enables (cabled) data transfer to any USB device.

The PX20 is supplied as a ready to go functional kit including a USB cable and lanyard. With its unique ergonomic design and weighing only 40 grams the PX20 is perfectly suited to being worn around the user’s neck with the lanyard supplied. Besides a modern and well thought-out design the PX20 has a drop resistance to 1.8 meters (no need for a special protection cover) and is IP 54. The PX20 is modern, fully functional and very durable, perfect for outdoor operations.

Armed with a variety of connection options and the ability to run customizable embedded applications created with the C-Library Kit.

The PX20 Bluetooth Companion Scanner enables real-time barcode scanning into any Bluetooth ready device.

Changing the Volume

To change volume options on your PX-20, please scan your desired setting from pages U124-125 in the Universal menu book. To use these settings, scan the SET barcode followed by your desired setting and then the END barcode.

Firmware Loading

There are multiple components to the firmware on an PX20 (Bootloader, OS and Application), however the instructions to load them individually or all together are the same. In most cases, all you'll need to do is load the OS, and the proper Application file for your needs.

Follow the directions below to load firmware on to the PX20.


  1. Download the Firmware: Bootloader, Firmware: OS, and Appload for this process available in the Software Downloads section. You may also need Opticon's USB Drivers, so please download those as well.
  2. Download the appropriate Firmware: Application file for your needs. This is most likely to be the Bluetooth Application, however there are other Applications available. A complete list can be found in the Downloads Section at the bottom of the page.
  3. Extract the PX20 Bootloader and Firmware - OS zip files, the Appload.zip file, the USB Drivers Installer.zip file, and the PX20 Firmware - Application files into a convenient folder.
  4. Install Appload by double-clicking the 'Appload Setup.exe' file, which will start the install wizard. The defaults are fine in most cases, so keep clicking 'Next' until you are finished. Appload will launch at the end of the install process.
  5. Connect the PX20 to your PC

Install the Firmware

  1. Launch Appload if it is not already running.
  2. We first need to choose the correct COM port. From the main Appload window, select 'Settings' > 'Port', then choose the port that says 'Opticon USB Code Reader'.
  3. Now we can start downloading the OS and Application. For each of the .hex files you downloaded and extracted above, please choose 'File', then 'Download', then navigate to and select the file. You should see a progress indicator and the words 'Initializing IRdA' if this is working.
  4. When complete the PX20 will emit a series of beeps and reboot. When the LED is steady RED (indicating charging) or GREEN (indicating fully charged) the process is complete and you may disconnect your PX20 from the PC. instruction manuals for the various applications are available for download in the Downloads section.

Alternative Modes

In addition to the CSP2 support built into the PX20, it is also capable of functioning as either a USB Keyboard or a USB flash drive. Both of these modes eliminate the need for PC software.

When in Keyboard mode, the PX20 can scan in real time or store data in memory which can later be transmitted at the push of a button. In flash disk(MSD) mode the PX20 stores barcode scans into a text file on the device. The text file can later be accessed simply by plugging in the device.

Batch Mode

This will make the scanner memorize the data and store it temporarily until the transmit data barcode is scanned

  • To put the PX20 in batch mode, Scan the +-MSTR-+ barcode. The device will then be in batch mode and will continue to store the data until the transmit data barcode is scanned.
  • To transmit the data and leave the device in batch mode scan the +-MXMT-+ barcode
  • To transmit the data and start scanning in real-time mode scan the +-MSTP-+ barcode
  • To clear all temporary memorized data off the scanner, scan the +-MCLR-+ barcode

Bluetooth Batch Mode Menu Commands

USB Keyboard Mode

This mode allows the PX20 to emulate a USB Keyboard. While the PX20 is plugged in, any barcodes that are scanned are input wherever the cursor is on screen. When a barcode is scanned while the PX20 is disconnected, the barcode is stored in memory. When you want to retrieve scanned barcodes, simply plug the PX20 into a computer, and press any key on the device to have it play back all of the barcodes that were scanned while it was disconnected.

To use the PX20 in USB Keyboard Mode, print and scan this barcode sheet. You may also need to update firmware to the latest version of the Firmware: OPN2001 Simulation Application to enable the feature.

USB 4.0 Bluetooth Low Energy Mode

Bluetooth Low Energy mode provides reduced power consumption and cost while maintaining a similar communication range as a standard Bluetooth connection. iOS, Android, Windows Phone, Blackberry, macOS, Linux, Windows 8, and Windows 10 all support Bluetooth Low Energy connection. To enable this connection on your OPN-2006, print and scan this barcode sheet from top to bottom.

Alternative Firmware

Storage Application (MSD Mode)

This mode is also referred to as USB-MSD mode. The Firmware: Storage Application must be loaded on the PX20 in order to enable this mode of operation. To install the Storage Application, follow these firmware loading instructions. Once the storage application is loaded, print and scan this sheet of barcodes to configure the device to act as a flash disk.

Once that's finished, scanning barcodes is as simple as pressing a button. When you want to download your barcode scans, plug the PX20 into a computer, and copy the text file out of the flash drive. For more configuration options, see the User Manual: Storage Application. In particular, the very last page has barcodes that can be scanned to configure the layout of the text file.

To delete the barcodes from you scanner, use the Format barcode in the above manual.

OPN2001 Simulation

To use the PX20 with the OPN Companion Application, first the Firmware: OPN2001 Simulation Application must be loaded on to the PX20. To install the OPN2001 Simulation Application, follow these firmware loading instructions. You may also need to print and scan this barcode sheet.

Return to Bluetooth Mode

To return the PX20 to Bluetooth mode, you will need to load the Firmware: Bluetooth Application. To install the Firmware: Bluetooth APplication, follow these firmware loading instructions.
